MARKING: IttEAQl-IINE.

Application filed May 3,

This invention relates to improvements in marking or stamping machines,and particularly to a machine of the character specified, designed formarking curved or irregular surfaces, for example, brush handles,although it will be evident from a considera tion of the followingspecification that my invention may be used for marl-:ing articles orobjects of various kinds made from differ ent materials.

The prime object of the present invention is to provide a simple andefficient machine of the character specified above, in which a die ormarking means is passed. over the surface of the article to be markedwith suflicient pressure to properly mark the desired surface and, atthe same time, so mounted to permit of the marking of curved orirregular surfaces. Further objects of the invention are to provide newand improved means for moving the die into and out of operativeposition, and to effect a marking in an expeditious manner; and toprovide common cooperating means for effecting a movement of the die tooperative position and the travel of the marking means over the articleto be marked.

Other objects and advantages will be hereinafter referred to or becomeapparent from a consideration of the following description taken inconnection with the drawings.

In the accompanying drawings, which illustrate an application of myinvention:

Fig. l is a side elevational view of a marking machine embodying myinvention;

Fig. 2 is a detail part ,elevational and a part sectional view taken onthe line ill-d1 of Fig. 1;

Fig. 3 is a detail top plan view, particularly showing the actuatinglinkage employed for reciprocating a roller die carrier,

Fig. 4: is a front elevation of the machine; and

Fig. 5 is afliagmentary side elevational View, showing the position ofcertain parts during the marking operation.

As illustrated and as preferred, my machine includes a suitable base 5having at one end thereof a standard or bearing 6, the latter beingdesigned to have pivotally mounted thereon a movable arm 7. Movablemember or rocker arm 7, as shown, comprises a curved main part havingcurved contacting edge portions or cam surfaces 8 and 9 and is providedat one end thereof with guides 10 designed to member or 192$. Serial No.274,7t3d.

receive and support a reciprocating diecarrier 11, the latter havingflanges 12 thereon for engagement with the guides 10. blecuredto theouter end of the carrier, I provide a depending forked member 13, saidmember being fastened to the carrier by a screw bolt 14; and designed tosupport a roller die 15 of any suitable kind, and upon which thecharacters to be marked on the article are carried.

it will be understood that my invention contemplates moving the die ormarker into and out of operative positions, relatively to the article tobe marked, which is retained in a fixed position; and, further, to causethe marker to be moved over the surface to be marked, and for thispurpose the mov able arm 7 and the carrier 11 are connected with meansfor manipulating and actuating the said members 7 and 11.

To this end, member 11 is slotted as at 1-6 to receive the end of a link17 constitutingan element in the linkage employed, and is tted at 1'? toreceive a pin 18 carried on a portion of the actuating means which lhave designated generally by the numeral 19. r v

The actuating mechanism, as illustrated, includes an upwardly extendingmovable arm or member 20, a transversely extending shaft 21 havingbearings in supports E21 attached to or formed integral with the base 5,to which the said member is fixedly secured by a pin a, and by which thearm 20 is adapted to be moved by revolving the shaft; a pivotallymounted member 22 disposed in a cutaway portion of the movable armmember 20 and mounted on the pin 18; saidmember 22 carries a contactroller adapted for rolling contact with the curved or cam surfaces 8 and9 of the arm .7 during the operation of the machine, as

will be more fully hereinafter described.

Attention is called to the tapered lower end 214: of member 22 and alsoto the fact that this inclined or tapered face is positioned on aninclined bearing face 25 of member 20 and that the said inclined facesare designed to be normally held in contact by means of a tension spring26.

Designed to cooperate with member 22 to control its movement, I providean adjustable stop member 27 adapted to he secured to the rocker arm 7by means of screws 28. lhe said stop 27 carries a spring pressedtripping trigger 29 having a small leaf spring 30; Trigger 29 ispositioned to engage a plate 31 mounted on the member 22.

Located intermediate the ends of the base are a pair of verticallyextending guide members 32, and at one end of the base it is w cut outto form a transversely extending members have tongues or flanges 40having sliding engagement with retaining plates 41 secured to the base.

42 designates an operating lever for rotating or partially revolving theshaft 21, and 43 indicates a-counter-balanced weight employed inconnection with the shaft 21.

For the purpose of imposing the desired weight or pressure on to themarking means, the arm 7 is connected with a weighted lever arm 45fulcrumed in bearing 46 by means of links or connecting members 47connected to arm 7 at their upper ends by a pin 48. These links extenddownwardly from arm 7 through an opening 49 of the baseand pivotallyengage the lever 45, as at 50. By providing a proper weight 51, thedesired pressure of the die roller 15 on the article,

I such, for example, as the handle B of a brushA, may be obtained.

It. willbe apparent from the above description that a movement of theshaft 21 and the actuating means, generally designated 19, may beeffected by a movement of dotted lines, Fig; 1. During this movement,

it will be apparent that the pin 18 will be moved from one'end of theslot 1'7 to the other end of said slot formed in the link 17. Duringthis last mentioned movement, member 22 is, by means of the stopmechanlsm including the trigger 29, tilted or rotated in acounter-clockwise direction, owing to'the fact that the said trigger 29is in locked position with the plate 31 of said member 22. It will beunderstood that further movement of the handle 42 in the I saiddirection will disengage the trigger 29 and plate 31 of member 22, thuspermitting .the arm 7 and its die roller 15 to be low- -ered until thedie roller comes intocontact with the brush handle B. This tiltingmovement of member 22 is against the tension After the die roller 15 islowered into operative position upon the brush handle, the desiredpressure or weight to effectively mark the article is obtained by theweighted fulcrumed lever 45 and the connections interposed between saidlever and the arm 7.

It will be noted that the downward movement of the arm 7 and the dieroller is effected by means of the weight applied thereto by theweighted lever -15, and that the limit of the marking movement will bereached when the contacting roller :23 of the member 22 reaches thepoint of juncture between the differently curved cam surfaces 8 and 9,as indicated at 52. After the roller 23 passes the said point 52, itwill be understood that the spring 26 will snap the member 22 into itsnormal position, as shown by the dotted lines, Fig. 1, and that theforward end of the rocker arm 7, together with the die carrier mountedthereon and the die roller, may be elevated from the brush, due to theaction of the weight 43. During this forward movement of the operatinglever 42, it will be seen that the die roller is lowered into operativeposition on the article to be marked, and will have traveled over thecurved or irregular surface and then raised therefrom. It will also beunderstood that by adjusting the stop member 27 upon the arm 7 thedesired distance of travel of the die roller upon the article to bemarked may be effected, and that, upon the return movement of theoperating lever, the parts of the actuating mechanism will assume theposition shown in Fig. 1, with the movable member 22 again locked by thetrigger of the stop mechanism.

To facilitate production, a mold may be clamped between the vise membersof the same, said mold shaped to receive the brush handle or otherarticle, and hence it will not be necessary to adjust the vise members'to article-engaging position each time an article is marked.
